"Hopefully the surgery will fix it," he added. "It's a pretty quick and easy operation."

Donald shared both the second- and third-round lead with eventual winner Rory McIlroy before his final-round 71 dropped him down a few pegs.

"I don't like to make excuses, but the last couple of days I've had the sinus issue again," said Donald. "I felt a little bit flat and unfortunately I couldn't get things going on Sunday."

He’d been going pretty good before Sunday, though – starting in 2011, Donald went an amazing 102 holes in a row without making a bogey in the Dubai tournament before dropping a shot on the third hole Sunday.
